Well, after some research I've realized some of my old headcanons are casually homophobic and I don't like that. I'm super sorry if I've offended you, and I'm going to try to fix it right now with these. Hopefully I can keep getting better at good representation. Please please PLEASE let me know if something is or could be offensive so I can fix it!
